England batsman Jonathan Trott has left the Ashes tour of Australia with a stress-related illness, the England and Wales Cricket Board has announced.
"Trott will take a break from cricket for the foreseeable future and will take no further part in the tour," the ECB said in a statement.
England's number three batsman Trott was a disappointment in this year's first Ashes series, averaging under 30 during the team's 3-0 triumph at home.
The lean patch continued as Mitchell Johnson bounced him out in both innings of the Brisbane Ashes opener, which Australia won comprehensively by 381 runs.
"I don't feel it is right that I'm playing knowing that I'm not 100% and I cannot currently operate at the level I have done in the past," Trott said in a statement.
"My priority now is to take a break from cricket so that I can focus on my recovery. I want to wish my team mates all the very best for the remainder of the tour."
Trott, who scored ten and nine at the Gabba, was in the eye of a media storm after Australia opener David Warner called the manner of his dismissals "weak".
England head coach Flower insisted that Warner's comments were not a factor in Trott's decision to return home but labelled the opener's outburst as "disrespectful".
When asked if Warner's comments had had a direct influence on Trott's exit, Flower said: "That would be inaccurate.
"As I said earlier, Jonathan has been struggling with this condition for quite a while and has managed it very successfully but we've been on tour for about a month.
"He's had his ups and downs through that month and it is not directly related to that.
"I would also say that I think players commenting about fellow professionals in the media is disrespectful.
"I think on this occasion he has got that horribly wrong.
"I think we set different standards to that and one of the reasons we don't like commenting about opposition players is because we don't know what is going on their dressing room, we don't know what is going on in their private lives."
